Useful:

• Chemical Classes: Solvents -> Chlorofluorocarbons
• Canonical SMILES: C(C(Cl)(Cl)Cl)(F)(F)Cl
• Inhalation Risk: A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20 °C; on spraying or dispersing, however, much faster.
• Effects of Short Term Exposure: Inhalation of high levels may cause lung oedema. The substance may cause effects on the cardiovascular system and central nervous system. This may result in cardiac disorders and central nervous system depression. Exposure could cause lowering of consciousness.
